MACPE: Mobility Aware Content Provisioning in Edge Based Content-Centric Internet of Vehicles

Abstract

Over the years, the Internet of Vehicles (IoV) and Information-Centric Networking (ICN) has gained significant popularity due to emergence of content provisioning in smart environments. The content provisioning in mobile and seamless environments is challenging due to frequent change in Point of Attachement (PoA) or handovers across the networks. In Edge supported IoV based ICN, the consumer’s interest packets are not satisfied until the producer re-connects to the new PoA and informs its current location to the next content router. The idea is to satisfy the interest packets by providing the requested data content to the consumer node at its current PoA. The existing ICN architectures without edge support within the zone do not handle and support mobility aware content provisioning to the consumers in the IoV environment. In this paper, we propose Mobility-Aware Content Provisioning in Edge-based content-centric Internet of Vehicles (MACPE). That manages the network in zones with content routers for up-to-date content and producer mobility information. The simulation results show that the proposed MACPE scheme outperforms GeoZone scheme in terms of benchmark parameters. i.e. packet delivery ratio, average end-to-end delay, handover delay, average hop count and throughput during producer mobility scenarios in intra and inter-edge-based zones.
